Theory of mind (ToM) reasoning is defined as the ability to reason about another’s internal states, such as beliefs, goals, and desires. It is a major aspect of human social interaction and is mastered by most typically developing children by age five. On the other hand, simulated agents generally lack...
Polymers with electrolyte groups or “polyelectrolytes” have been the subject of intense study for the past few decades due to characteristics such as anti-fouling and underwater adhesion. Because of their charged nature, however, polyanions and polycations will complex in aqueous solutions forming dense unprocessable precipitates. In an attempt to leverage...
Recognizing the significance of social interactions in shaping human behavior and development, policies and programs often rely on peers and social relationships as mechanisms for inducing positive change. Yet, even in randomized control trials, social spillover can make an effective program appear ineffective, and measuring peer effects poses identification...
When properly regulated, inflammation leads to the recruitment and activation of circulating leukocytes to maintain and restore tissue homeostasis. Although this process is critical for successful wound healing and the elimination of pathogens and infections, misdirected inflammation can exacerbate pathology and cause substantial morbidity and mortality. Inflammation a fundamental process...
High performance polymers and their composites have wide ranging application in advanced and emerging material systems. The macroscale performance of these advanced materials is often defined by interfaces that induce nanoscale changes in the microstructure or molecular conformations (termed the ‘interphase’) of the polymer. Atomic force microscopy (AFM) is an...
This dissertation examines how China’s involvement in transnational LGBTQ activism, adaptation and innovation of queer media technologies, and the global pink economy have influenced queer men’s understandings of selfhood, sexual desires, and the relationships among queer subjects. It is based on extensive fieldwork in Beijing and digital ethnography on China’s...
The nonlinear attributes of cochlear function are fascinating. Responses are compressed with surprisingly little distortion, different stimuli interact in competitive ways, and tones are created either with or without acoustic stimulation. Moreover, because of their dynamism, these nonlinear phenomena have provided an invaluable means for noninvasively probing and understanding cochlear...
4D Flow MRI is a phase-contrast magnetic resonance imaging method that enables direct measurement of velocities in three orthogonal directions throughout the heartbeat. This permits direct quantification of hemodynamic parameters, including flow, mean velocity, peak velocity, and pulsatility, for individual cerebral vessels. Despite ongoing research into neurovascular applications of 4D...
We present two novel, computational models of biofilm growth within an experimental flow cell. First, we use asymptotic approximations to develop a reduced model that captures the large-scale dynamics within an entire flow cell. The reduced model's predicted growth and nutrient distribution are close to the values predicted by previous...
Down syndrome occurs in approximately 1 in 700 births annually in the United States. It is caused by trisomy of chromosome 21, and is characterized by dysmorphic features and congenital abnormalities. Although children with DS have a decreased risk of developing solid tumors, they have an increased risk of acquiring...
